UNITED STATES PATENT FFICEQ IRVING BARKER, OF BRAIDWOOD, ILLINOIS.

SELF-LUBRICATING CAR-WHEEL.

SPECIFICATION forming part of Letters Patent No. 372,290, dated November1, 1887 Application filed March 14, 1887.

To all whom, it 11mg concern:

Be it known that I, IRVING BARKER, a citizen of the United Statesof'America, residing at Braidwood, in the county of \Vill and State ofIllinois, have invented certain new and useful Improvements inSelf-Lubricating Car- Wheels, of which the following is a specification,reference being had therein to the accompanying drawings.

This invention relates to certain improvements in a self-lubricatingcar-wheel, which lmprovements are fully set forth and explained in thefollowing specification and claims, reference being had to theaccompanying drawings, and the letters and figures of reference thereon,making a part of this specification, in Which-- Figure 1 is a side planview of the wheel having its detachable cap removed. Fig. 2is a centralvertical cross sectional view of the wheel and its detachable cap, andshowing an axle-stub properly journaled in the wheel. Fig. 3 is asimilar view of the cap detached from the wheel, and drawn on a largerscale. Fig. 4 is an outside face plan view of said cap. Fig. 5 is aninside plan View of said cap, and Fig. 6 is a side view of said cap.

Referring to said drawings, WV represents a car-wheel the hub H of whichis constructed with an annular oil-chamber, O, surrounding its box,extending from about the center of the hub to its forward end and castwith the front of said oil-chamber open, and O are equidistantlongitudinal partitions in said oil-chamber, extending from its rearwall to near the front end of the box, but not across said oilchamber. Dis a detachable cap for closing said annular chamber 0, and forms itsouter walls, and its hollow, together with said annular chamber (3,forms a receptacle for a lubricantforthewheel. Aisan axle-spindlesecuredin the box of the wheel by means of a linch-, 'pin in the ordinarymanner.

The outer wall, F, of said chamber 0 is flared outward, as shown in Fig.2, and the cap D is provided with an annular flange, R, which is taperedto correspond with the flared form of said chamber 0, as shown in Fig.3. P is a packing surrounding said flange R. Said cap. is secured to thewheel-hub by means of forcing Serial No. 230,816. (No model.)

be forced within said chamber to the proper distance. Said cap D isprovided with an oilhole, 0, for feeding the oil-receptacle, whichoilhole is closed on its inner side by means of the valve P, held by thespring S, secured to the inner side of flange R, as shown in Fig. 3.Said spring permits said valve to be pressed inward by the spout of anoil-can when it is desired to supply oil to the oil-receptacle, andclose said oilhole when the can-spout is.removed. Said oil-hole 0 may beclosed by means of a spring-stopper, T, as shown in dotted -lines inFig. 3, if desired. Said cap is also provided with lugs L L, as shown inFigs. 4

and 6, which lugs furnish means for removing said cap by means of alever.

The principal new feature in this invention consists in having the outerwalls, F, of the chamber 0 flared outward, andthe cap Dhaving, itsflange, R tapered to correspond with the flared walls of said chamber,and securing the cap to the wheel-hub by means of forcing its flangewithin the flared wall of said chamber O, (a packing having first beenplaced between said flange and wall,) and thus hold the cap in placesimply by its adhesion with the chamber into which its flange is forced,and thus dispense entirely with the use of bolts or screws for thatpurpose.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is as follows, to wit:

1. The self-lubricating car -wheel shown and described, having theoil-chamberO surrounding its box and cast with its front open, and itsouter wall, F, flared outward, said chamber having the equidistantlongitudinal partitions 0 extending from the rear wall to near the frontend of said box, but not en- IOO with the cap D, having the flange Rtapered to correspond with the flared wallet said chamher, and having anoil-hole, 0, provided with means for opening and closing said oil-hole,and the packing P, between said flange and wall, substantially as setforth.

2. The combination of the wheel XV, having the chamber 0, surroundingitsbox, and having its outer wall, F, flared outward, and the IO cap D,having its flange R tapered to correspend with the flared wall of saidchamber and adapted to close said chamber 0 by means of forcing saidtapered flange within said flared chamber, substantially as and for thepurpose set forth.

IRVING BARKER.
